As early as 1920s, a financial expert of Chicago Mafia bought a coin-operated washing machine and opened a laundry. Every night, when he settled the laundry income that day, he added the illegal money and then declared the tax to the tax bureau. After-tax money becomes his legal income, which is the origin of the word "money laundering".
Regarding the punishment of money laundering, the Amendment to the Criminal Law stipulates that anyone who knowingly commits the crime of financial fraud in order to conceal the source and nature of the proceeds from drug crimes, organized crimes of underworld nature, terrorist activities, smuggling crimes, corruption and bribery crimes, and crimes of disrupting financial management order shall be confiscated, and shall be sentenced to fixed-term imprisonment of not more than five years or criminal detention, and shall also be fined at least 5% of the money laundering amount. If the circumstances are serious, he shall be sentenced to fixed-term imprisonment of not less than five years and fined not less than 5% but not more than 20% of the money laundered.
